Features IntelliPower, a finely tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance.

64MB cache buffer.
The cache buffer can hold the results of recent disk reads, and "pre-fetch" information that is likely to be requested in the near future. This helps minimize the mechanical latency of acquiring the requested data from the disks. It also enables the hard drive to cache data that has been requested to be written to the hard drive, enabling efficient reordering and writing of the data to the disks.
